Specification of Letters Patent.

Application filed October 27, 1916. Serial No. 128,074.

T 0 all whom it may concern:

Be it known that I, CHARLES C. HOLE, a citizen of the United States, residing at Fremont, in the county of Dodge and State of Nebraska, have invented new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to improvements in wrenches which may be used for either plpe wrenches or nut wrenches as desired; and the invention consists in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended clalms.

In the drawings:

Figure 1 is a side elevation of a wrench constructed in accordance with the present invention,

Fig. 2 is a edge view thereof,

Fig. 3 is a sectional view taken approximately on the line 33 of Fig. 2,

Fig. 4 is a perspective view of the stationary jaw, one of the side plates thereof being removed and the aw block being shown in section,

Fig. 5 is a perspective view of the sliding jaw, and

Fig. 6 is a perspective view of the key or holder member for the trunnion of the handle.

The wrench embodies essentially a stationary jaw 8 having one or both of its sldes integrally formed with plates 9. If desired one of the plates only may be formed upon the jaw and the other plate may be connectmovable jaw 11. One of the plates 9 adjacent its juncture with the jaw 8 is formed with a longitudinally extending rib 11 to receive a longitudinallv disposed groove 12 upon the shank of the movable jaw. The other plate 9 is provided with an elongated slot or opening 13 within which is arranged a pivot or stop pin 14:, carried by the shank 10 of the movable jaw, and the contact of this pin with the opposite ends of the slot 13 limits the movement of the slidable jaw with relation to the stationary jaw.

What may be termed the outer edge of the shank 10 is formed with spaced teeth 15.

Each of the side plates 9 of the stationary jaw 10 is centrally provided with an angular or cam shaped slot 15' within which are received the trunnions 16 provided upon the rounded head 17 of a handle member 18. The head of the handle is peripherally formed with teeth 20, whereby to engage with the teeth of the shank of the movable jaw and to slide the jaw toward or away from the stationary jaw. When the trunnions 16 are in the off-set portions of the slots 15' the teeth of the handle will be brought to mesh with the teeth of the shank of the movable jaw and when the trunnions are brought to within the 1011- gitudinal portions of the slots 15, indicated for distinction by the numeral 21, the teeth of the handle are brought out of engagement with the teeth of the said movable jaw. By this arrangement it will be noted that the handle may be quickly adjusted to any number of different angles independent of the position of the jaw and also that the jaws will automatically adjust themselves to the nut or to another article engaged therebetween when the handle is moved in the direction that the nut or article is to be turned.

Disposed for travel in a groove 22 arranged in one or both of the side plates of the stationary jaw is a substantially rectangular member 23 that has its reduced end extended outwardly of the wrench and has one of its ends provided with an offset extension 24. This extension or enlargement 24 is normally brought to engage with the trunnion 16 of the handle through the medium of a spring 25 which forces the member 23 in one direction; that is, outward of the wrench, whereby the longitudinal portion 21 of the slot 15 is normally closed and the teeth of the head are retained in engagement with the teeth of the shank. By pressure upon the outer end of the member 23 which may be provided with a knob 26, the said member 23 will be moved against the tension of the spring 25 so that the reduced portion thereof will be brought to aline with the lower or outer edge of the referred to portion 21 of the slot 15 permitting the trunnions to fall by gravity to within the slots or the handle to be moved to bring the trunnions to such positions, and whereby the teeth of the handle are brought out of engagement with the teeth of the shank. The wall or shoulder between the widened portion 24, and the member 23 is rounded, as at 27, and when pressure upon the handle as well as pressure upon the knob 26 is relieved the member 23 will be autosaid shank and movable matically moved by the spring 25 to raise the handle or to move the same so that its teeth will engage with the teeth of the movable jaw.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is tliought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what I claim is:

1. In combination, a stationary jaw having ai'ig'ularly arranged spaeed side plates; a movable jaw having its shant disposed for longitudinal, movement between the side plates, means for limiting the movement of the said movable jaw with relation to the stationary jaw, guide means for the movable jaws, the shank of the movable jaw being toothed, a handle having a rounded head provided with peripheral teeth disposed between the side plates, trunnions upon the head of the handle, the side plates having cam slots to receive the trunnions, and means comprising a longitudinally movable spring pressed member engaging with the trunnions for normally forcing the sarne in one direction within the cam-shaped slots to bring the teeth of the head to mesh with the teeth of the shank.

2. In combination with a stationary jaw having angular side plates, and a movable jaw having a toothed shank disposed for longitudinal movement between the said plates, each of said side'plates having registering angular slots, a handle member having a rounded toothed head disposed between the side members, said handle having its head provided with laterally extending trunnions which are arranged within the angular slots, of a member arranged in bearings in the side plates, an offset extension iipon one of the ends of said member, and the wall between the said extension and the said member being rounded, means comprising a spring for normally moving the member in one direction to bring the offset portion thereof to engage with the trunhions of the head, whereby the teeth of the head are normally in mesh with the teeth of the shank of the movable jaw, and Said member having its end opposite that provided with the offset portion projecting outwardly of the wrench.

In testimony whereof I afiiX my signature.
